In your latest example (I'm going to refrain from making fun of your mental illness), it won't work because a 48W water pump can only pump water with up to 48W of energy. That 48W of energy can not turn a 2000W generator. You COULD potentially hook up about 100 of these water pumps, and if they are VERY efficient could POTENTIALLY turn a 2000W generator, but you're spending 5000W to do it.
